Having survived 120 scoreless minutes thanks to a breathtaking extra-time save from Stefan Frei, the Sounders saw defender Roman Torres convert the winning spot kick as they triumphed 5-4 in penalties over Toronto FC.
Each team went 4-for-5 in the initial set of penalties — Jozy Altidore, Benoit Cheyrou, Will Johnson and Drew Moor converted for TFC, while Brad Evans, Andreas Ivanschitz, Joevin Jones and Nicolas Lodeiro fired home for Seattle. Each goalkeeper made one stop, as Frei denied Michael Bradley and Clint Irwin stoned Alvaro Fernandez.
As the shootout went to sudden death, Toronto's Justin Morrow rang the crossbar. With the MLS Cup on the line, Torres calmly roofed his shot to stun most of the 36,045 fans at BMO Field and trigger euphoria on the Seattle sideline.

After 90 minutes of Toronto dominance failed to produce a goal, the home side thought it had the winner early in extra time. Substitute Tosaint Ricketts got down the right flank in the 109th minute and hit a service to Altidore, whose looping header was seemingly destined for the far corner.
But Frei reached back, got his fingertips to the ball and remarkably scooped it out of harms way inches before it would have crossed line.
While Torres got to enjoy the trophy-clinching moment, it was Frei's stop that set the stage for the Sounders to finally bring an MLS Cup back to Seattle.
